When I test pybullet environment in PPO Algorithm, I got this issue. But I train in the pybullet environment, There is no problem here.

Code:

  File "/home/me/PPO/src/policy_gradients/agent.py", line 447, in run_trajectories    initial_states = self.reset_envs(envs)  File "/home/me/PPO/src/policy_gradients/agent.py", line 383, in reset_envs    return cpu_tensorize([env.reset() for env in envs]).unsqueeze(1)  File "/home/me/PPO/src/policy_gradients/agent.py", line 383, in     return cpu_tensorize([env.reset() for env in envs]).unsqueeze(1)  File "/home/me/PPO/src/policy_gradients/custom_env.py", line 99, in reset    start_state = self.env.reset()  File "/home/me/anaconda3/envs/state/lib/python3.7/site-packages/gym/wrappers/time_limit.py", line 27, in reset    return self.env.reset(**kwargs)  File "/home/me/anaconda3/envs/state/lib/python3.7/site-packages/pybullet_envs/gym_locomotion_envs.py", line 30, in reset    self._p.restoreState(self.stateId)pybullet.error: Not connected to physics server.
